Halloween LED light boxes: 5 steps (with pictures)



Now that we have an SVG file with the image, we open the design software (Tinkercad) and import our image; dimension it as desired for the building dimensions or intended purposes. I used 150mm x 90mm for this one. Mostly an arbitrary number on my part, but you must be aware of the size of your 3D printer's building platform and your desired size. Too large and the LED does not light enough and it loses power too little. I made the pumps 2.5 mm high so that I can print two colors in this design. I have to make time to change the filament and still have enough thickness to completely block the light emitting from behind.

Since I chose a size of 150 mm x 90 mm, I will simply make a support plate, white part of the image, the same dimensions, but it will only be 0.75 mm high. This means that it is thin enough for the light to pass through and gives the 1

.75 mm pumps silhouette above to provide contrast.

Now that the dimensions are set for the "photo", I can build the box (picture frame) to hold photos, batteries, wires and LED lights. I create a box that is just slightly larger than the photo plate and deepen the top a bit to hold the picture plate in place. The box must also be deep enough to hold the battery holder between the wall on which it hangs and the front image plate. I used a battery holder that I designed to hold two AAA batteries in series and thus gave 3V output. I then add a notch on the top and back of the box to hold it on a wall when I hung on a nail or screw head.

Note: I did not include any of the design files simply because none of the original artwork used was my own design. I changed the original photos and added or subtracted from them in some cases, but I am not comfortable sharing photos that I am not the only designer of.
